Takeda | May 29, 2001 |
A golf club which is so light as to be large-sized, with an improved durability, suited for easy casting. Ti--Be alloy is used for the material of a head 1. Be is present in Ti as a TiBe and/or TiBe.sub.2 in a proportion of about 20 mol %. The use of such Ti--Be alloy will result in the lightening of the head 1 as well as the enhanced Young's modulus thereof, thus improving the durability thereof. The Ti--Be alloy has such a lower melting point of 1000 degrees centigrade or below as compared to pure titanium, that the casting thereof is easy.
